Are you having trouble finding the downloaded extensions? When using the MyDSL interface (the desktop icon), the extensions are saved to /tmp by default. You will need to copy the ones you want to keep into a place where they can be found during the boot process (as stated at the first link).The extensions will need to be saved in the format in which they were downloaded (*.dsl, *.tar.gz, *.uci, *.unc) or they will not load when you boot.
